Here you will find Audio Oriented projects, many in the German Language. There is one – Converting Analog into Digital (IIR) Filters which is useful for Mixed Design students. Then there is a FPGA-Based Digital Audio Peak Level and Correlation Meter with many features. The Hi-Fi Audiophile will like the Tools – Audio Preamplifier, Weighting Filter Set and Universal Filter.

“It is very well known what kind of deviations from the original signal a human ear is able to hear (e.g. distortion, frequency response, noise etc.) and also in which amount and under which circumstances this is the case. All these deviations from the original signal are measurable with a precision and sensitivity far, far superior to the human ear….”

Delta sigma converters are different from other converters. Note that I do not make a difference between analogue-to-digital (ADC) and digital-to-analogue converters (DAC). Both are very similar and what is realized in one of them using analogue signal processing circuitry is implemented in the other one using digital signal processing and vice versa. I will explain the delta sigma technique with the analogue-to-analogue delta sigma converter as the first object.
